Ask her some things like:
Are you a morning person?
Do you have a set schedule?
Do you do any clubs or sports?
Do you have any food allergies?
Do you want each of us to bring fridges, or do we want to share one?
What kind of music do you like?
Do you think we can fit a couch in our room?
Do you want to bring fish?
Do you drink? (Smoke, sniff fish at midnight?)
Should I expect regular visitors/people sleeping over?
(for the bravesmile What kinds of nudity are okay, and what would make you uncomfortable?
How often would you be visiting home?
Dude, you're making it awkward. Just show up and don't talk to them beforehand. I mean I suppose just ask what appliances they are bringing that they are willing to share... most awkward thing that could happen is ending up with two toasters.
